Sony Ericsson Aino is touch screen based slider phone. It has a multimedia PS3-inspired touch menu, a large 3-inch (76 mm) touchscreen, VGA@30 frame/s video recording. The 3-inch (76 mm) screen is touch-enabled but only in the multimedia part of the menu and the camera interface. Some third party applications like Opera-Mini also support the touch screen interface. It also has an 8.1-megapixel camera.

Like the Sony PSP, the Aino features PlayStation 3 connectivity, called Remote Play. This allows the phone to be able to turn the PS3 on from anywhere in the world and stream its media files. This is the first phone to implement this, as it was previously only available on PlayStation Portable.
